Association of Survival With Adjuvant Chemotherapy Among Patients With Early-Stage Non–Small Cell Lung Cancer With vs Without High-Risk Clinicopathologic Features

Abstract

In this cohort study, tumor size alone was not associated with improved efficacy of adjuvant chemotherapy in patients with early-stage (node-negative) NSCLC. High-risk clinicopathologic features and tumor size should be considered simultaneously when evaluating patients with early-stage NSCLC for adjuvant chemotherapy.
